  • 摘 要:国家标准方法测定锌精矿中锌、铁需单独溶样,步骤繁琐、流程长,研究建立锌精矿中锌、铁的连续测定。实验采用一次溶样,EDTA标准溶液滴定锌、铁。经国家标准物质进行验证,测定结果的相对标准偏差为0.14 %1.02 %,相对误差0.23 %1.56 %,该方法精密度高、准确性好,且流程简单,适合大批量锌精矿中锌、铁的连续分析测定。

    Continuousdetermination of zinc and iron in zinc concentrate……Yang Fengping,Zhang Yu,Liu Huali,Wang Lichen,Li Yanhong,Kan Chunhai,DongShuang

    AbstractNational standard method for zinc and iron determination in zincconcentrate requires independent sample dissolution and thus has lengthy stepsand flow sheet.So a method for continuous determination of zinc and iron inzinc concentrate was set up.The experiment dissolved the sample in a singletime and zinc and iron were titrated in EDTA standard solution.Verified by thedetermination of national reference material,the determination method isaccurate and precise with the RSD of the determination results being 0.14 %-1.02% and relative error being 0.23 %-1.56 %.Besides,the method is easy andshort,applicable to continuous determination of zinc and iron in batch zincconcentrate samples.

    Keywords:zinc concentrate; zinc; iron; sample dissolution; continuous determination
